The boiling point depends on the strength of the intermolecular forces holding the molecules together. Greater the force, higher is the boiling point.
The intermolecular force increases in the order shown below:
ion-ion > H-bonding > dipole-dipole > London dispersion
CH3CN is a polar molecule with strong dipole-dipole forces
CH3CH2CH3 is non-polar held by london dispersion
Ar exist as a gas. It will have a lowest boiling point
Thus the order of decreasing b.pt is:
CH3CN > CH3CH2CH3 > Ar
Answer:
Fossils are remains or traces from ancient life's that is most likely buried in rocks anywhere in the world. Fossils are basically bones, teeth, shells, nests, leaf impressions, and footprints. That is technically explaining what our planet was like long ago. Some dinosaur fossils have been found. Paleontologists find them almost everywhere. If you don't know what Paleontologists are, they're basically people who study fossils. A lot of fossils are found in sedimentary rocks. Sedimentary is a rock that has been formed from things like sand, mud, and many other kinds of rocks.
Hope this helps.
T k = 15 + 273 = 288 K
4.6 / 13 => 0.353 atm
0.50 / 0.10 => 5 L
<span>(15 + 273) K x (13 atm / 7.6 atm) x (0.50 L / 0.10 L)
</span>
<span>= </span>2463.15 K

apply quantum theory to, especially form into quanta, in particular restrict the number of possible values of (a quantity) or states of (a system) so that certain variables can assume only certain discrete magnitudes.
The equation that is represented by the model is = x²-2x-3=(x − 3)(x + 1).
<h3>What are polynomials?</h3>
Polynomials are defined as the mathematical expression that is made up of variables.and coefficients.
The model is +X-x-x- ,
Which is X -2x ( negative minus negative is plus)
Therefore, the equation that is represented by the model is = x²-2x-3=(x − 3)(x + 1)
